Isolation, Genomic Characterization, and Immunogenicity Evaluation of a G9P[23] Porcine Rotavirus Strain.

ABSTRACT: (1) Background: Rotavirus (RV) is the primary pathogen causing diarrhea in infants and young children. The G9-type is an emerging genotype; however, its isolation is challenging, and its immunogenicity to piglets is poorly understood. This study aimed to isolate, characterize, and evaluate the immunogenicity of a PoRVA strain, RHeN2, obtained from the diarrhea samples of piglets from a pig farm in Henan Province, China. (2) Methods: Porcine rotavirus A (PoRVA) was isolated from diarrheal samples of piglets on a farm in Henan Province, China, through sequential passaging on MA-104 cells. Its immunogenicity and cross-neutralization potential were evaluated. Inactivated vaccines were prepared using two agents (formaldehyde and binary ethyleneimine, BEI) and administered intramuscularly to 28-
